Rotary dialer in modern cell phone

I want to merge rotary dialer with a modern cell phone. Can anyone help me with this, please? Actually I have to convert rotary dialer's analog signals to cell phone's way of dialing -- key closing...

I think it's possible to implement this to cell phone+rotary dialer

You have to have a pulse counter that returns a 2-tone based on the count (1-10) or close one of 10 switches and reset itself. It would also have to trigger a "send" switch after an alloted delay after the last pulse. Yea. I've seen the Retro Phones too. It would be a cool project!
